REENFORCEMENT-FOR ICE-CREAM TUBS AND METHOD OF MAKING SAME.

Application filed June 3, 121. Serial N0. 474,789.

To all whom it may concern:

Be it known that l, Lnwrs ROMAN, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Reenforcements for Ice- Cream Tubs and Methods of Making Same, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to reenforcements for ice cream tubs or the like, the invention in the form here shown being a modification and improvement of the devices illustrated and described in my copending application for patent Ser. No. 371,385, filed April 5, 1920, and in United States Patent No. 1,378,722 issued to me May 17, 1921.

Reenforcements for the bottoms of ice cream tubs in the forms illustrated in my copending application for patent and my issued patent above referred to have come into extensive use,-a substantial industry having been built up in practicing the inventions in these two forms in connection with the maintenance of the tubs of ice cream manufacturers and dealers. Experience with reenforcements of this type, however, has taught that itis desirable to provide reenforcements with flat bottoms,- thus the construction illustrated in my issued patent above referred to in which the bottom of the reenforcement consists of fiat overlapping portions of metal welded one to the other, is a substantial improvement in this respect over the construction illustrated and described in my copending application in which the bottom of the reenforcement is corrugated. It has been found, however, that heavy and constant shocks exerted on the welded type of bottoms will result in time in breaking open the welded joints, thus permitting the adjacent edges of the metal to become displaced and to project downwardly beyond the normal plane of the bottom. and creating an obviously unsatisfactory condition of the tubs.

To overcome this condition, I have de veloped an improved reenforcement, as herein illustrated and described, which consists of an integral piece of sheet metal having an unsplit attaching flange or hoop and a flat, unsplit bottom flange adapted to cover the lower ends of the staves and the outer portion of the bottom of the tub.

Special dies are required in the manufacture of reenforcements of this type to compensate for displacement of the metal and to effect a smooth, even surface of both flanges; also a special process is employed, as herein illustrated and described, for adapting and attaching the improved reenforcements to the tubs.

In the accompanying drawings:

Fig. 1 is a detail view illustrating the first step in production for manufacturing the reenforcements Fig. 2 illustrates the second step in production;

Fig. 3 illustrates the method of expanding the hoop flange, and

Fig. 4: illustrates the method of applying the reenforcement to an ice cream tub.

In the form here shown my invention is of very simple construction, consisting of an unsplit attaching band or hoop -1 which is formed integrally with an unsplit bottom reinforcing flange 2, the remaining portion of the bottom being cut away as at 8 to prevent moisture accumulating in the bottom of the reenforcement. The reenforcement is attached to a tub by means of rivets or hoop nails 4 which are driven through suitable apertures 5 in hoop 1 into the staves, thus securing the reenforcement to the tub.

The reenforcement, being made from dies, comes exact to size and, therefore, when manufactured in quantities, is made somewhat under size to permit of expanding the hoop to the required diameter to fit the tub,this being done, as illustrated in Fig. 3 by tamping out the metal of the hoop by hammer blows until it is brought to the required dimension to form a driving fit on the tub as illustrated in Fig. 4.

From the foregoing detailed description and the illustrations of the drawings the practice of my invention in its present improved form will be readily understood. It will be seen that the reenforcement is simple and cheap to manufacture, that the method of applying the same to ice cream tubs is practicable and inexpensive, and that the unsplit reenforcement thus applied forms an effective protection which will greatly prolong the life of the tubs and minimize the cost of maintenance.

Having described my invention, I claim:

1. A reenforcement for ice cream tubs, comprising an unsplit hoop adapted to be expanded to form a drive fit over the lower portion of the metal upwardly at a suitable angle to form an unsplit hoop flange of said portion, in expanding the same variably and in forming an inturned bottom flange of the remaining portion of the metal substantially at right angles to the hoop flange,

and in maintaining a smooth, even surface of the metal in both flanges.

3. The herein described process ofmanufacturing reeni'orcements for ice cream tubs, or the like, consisting in forminga reentorcement comprlsing an unsplit hoop and bottom flange formed integrally one with the other, in expanding the hoop flange, and in effecting a drive fit of the same on the lower end of a tub.

In testimony whereof I aiiix my signature.
